Title (EN) PROCESS FOR REMOVING OXYGENATED CONTAMINANTS FROM HYDROCARBON STREAMS
(FR) PROCEDE D'ELIMINATION DE CONTAMINANTS OXYGENES DE COURANTS D'HYDROCARBURES
Abstract: front page image
(EN)Process for selectively removing oxygenated contaminants from streams prevalently containing hydrocarbons with from 3 to 8 carbon atoms characterized in that it comprises an adsorption step wherein said contaminants are adsorbed by an adsorbent essentially consisting of silica gel at a temperature of between 0 and 150 °C and a pressure of between 1 and 20 atms and a regeneration step for removing the adsorbed substances by thermal treatment in a stream of inert gas carried out at a temperature of between 100 and 200 °C.
(FR)L'invention concerne un procédé visant à éliminer de manière sélective des contaminants oxygénés de courants contenant de manière prévalente des hydrocarbures possédant de 3 à 8 atomes de carbone. Ce procédé se caractérise par une étape d'adsorption dans laquelle les contaminants sont adsorbés par un adsorbant, contenant principalement du gel de silice, à une température comprise entre 0 et 150 °C et à une pression comprise entre 1 et 20 atm, et par une étape de régénération dans laquelle on élimine les substances adsorbées par traitement thermique dans un courant de gaz inerte à une température comprise entre 100 et 200 °C.
